ISL9012IRCJZ-T

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The ISL9012IRCJZ-T is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation. It integrates two independent LDO channels within a compact 10-lead DFN package measuring 3mm x 3mm. The first channel provides a fixed output voltage of 2.8V with a maximum continuous current capability of 150mA. The second channel delivers a fixed output voltage of 2.85V, supporting up to 300mA of output current. The device operates with an input voltage range from 2.3V to 6.5V and maintains functionality across a temperature range of -40°C to +85°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct output voltages and packaging options. Confirm availability status through authorized distributors, as this component may be subject to limited stock or end-of-life transitions. Request updated manufacturing documentation to validate compliance with current environmental standards before finalizing procurement orders.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when designing circuits requiring dual isolated voltage rails from a single input source. Ensure the total load current does not exceed individual channel limits while maintaining adequate input-to-output voltage differential. Verify that the external capacitor ESR remains within specified ranges to guarantee stability without oscillation during transient load conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the ISL9012 series of dual LDO regulators designed for space-constrained portable electronics. The series emphasizes low noise and high PSRR performance suitable for sensitive analog and RF sections in mobile devices. The DFN package facilitates surface-mount assembly while minimizing board footprint requirements compared to traditional leaded packages.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

The ISL9012IRCCZ serves as a pin-compatible alternative within the same product family. Verify that the substitute matches the required output voltage tolerances and current ratings for both channels before implementation.
